Zeitschriftenaufsatz / Fach: Chemie
The electronic transitions of the various chromophores of 22,23-dihydrobufadienolides I (R1 = H, R2 = H, SMe, SPh; R1 = SMe, SPh, R2 = H) are assigned. The configuration at C-23 of I (R1 = H, R2 = SMe, SPh; R1 = SMe, SPh, R2 = H) was detd. by 1H NMR, CD, and x-ray methods.
